l Application filed March 1,1917. s rial no. 151,780.

To all whom it may concern:

LEVIN, of. the city of WVinnipeg, in. the Province of .Manitoba, Canada, have invented eer tainnew and useful Improvements inWindow-Blind Attachments, of which the; following is the part of the window .whileallowing of the admission of; light orof a View through the remaining part or parts ofthe window.

' vlVith the above objects inlview the inventionveonsists essentially in a ,pair of guides secured to the window frame at the sides,

adjustable,telescoping, tubes extending betweemthe guides; wheels atthe ends of the tubes and operating in. the guides, travelers slidably mounted in. the guides and provided with extending ;.blindholders and meansfor adjusting the ;.,wheels in vertical position inrespect to the guides, the parts being arranged, and constructed as herein;- after more particularly describedandlater pointed out in the appended claims, referencebeinguhad t0 the. accompanying drawing inwhich ;Figure; 1 represents an interior view of a windowv supplied with my invention.

Fig. 2 represents a, horizontal sectional view through thewindow and attachment.

.Fig. 3 represents an enlarged detailed horizontal sectional view through a guide and adjoining parts.

Fig. 4 represents a perspectiveviewsof one of the travelers.

Fig. 5 represents a fragmentary view of a portion of one of the plates on the guides.

Fig. 6 represents a sideyiew of" one of the wheels.

In the drawing like characters of reference indicate corresponding, parts; in ,the 1 spindles, be1ng spaced a short distance and several figures. 1 and 2 represent the usual uprights or side members of a window frame, 3 the upper cross member and 4 the sill.

5 represents the window which as usual 7 comprises top and bottom sashes.

Ordinarily the View or light is regulated by a window blind mounted on the window frame at the top the blind beingv pulled down a greater or. less distance as, wished. ,lVith this erlian gement, if -one draws the blind to exclude light or. vision; through. the lower part of the window henecessarily excludes light or vi through the top part of the window. I r

, With. my construction it is-possible forgone to have the vlowerpart of the window closed by the blind and the'up'per part ,open to allow of the entrance of light or vision through, the Window.

ciated.

Further one can adjust thegblind in,the

central portion ofthe window while having thefupper partand the lower partv open. I .will .now describe inyn appliance y (iand 7 represent a.pair'ofuprightguides permanently secured such as by nailingto This is a. ver;-y irnportant feature as will be readily apprethe sidesof the ,windowL-frame- These guides, in the presentinstance, are ofchannel irOn construction thereby providing in each a.pair ofspaced runways Sand 9; The runway .9 of each, guide is fitted with a permanent vertically disposed carrier plate 10 which. is perforated throughout, its

length toprovide. spaced openings 11, the

said; plates actually forming racks. ln this connectioml-wish it to be understood that I donot wish to belimited to the precise formation offthese carrier plates as they could bereadily modified while embodying the rack idea Without in the least departing from the spirit of my invention.

Betweenthe guides and crossing the window I locate an adjustablespacing member 12 formedfro'm a tube 18 telescoping within second tube 14, there. being a jann screw .15 suppliedtoallow .ofthe adjustment of the tubes in; length. The outer ends of the tubes are eachv plugged with .a short extending spindle 16, which ,is permanentlyfastened to the tube by a cross pin l7. When properly adjusted, .these. spindles extend; within the guides.

A toothed wheel 18 is permanently se-" curedsuch as by aS pin 181 to each of the as best shown in Fig. 3 from the end of the tube. The wheels are arranged to operate on the racks with the teeth rolling in the wheel, I mount a traveler 19, which traveler has the opposite sides thereof 20 and 21 parallel and adapted to contact with the inner faces of the plates 8 and 10, these plates actually forming slides for the travelers. 7

Owing to this arrangement it will be seen that when the member 12 is raised and lowered the traveler plates will have to move up and down in the guides, and that they are allowed no tilting action. Each traveler is supplied with an extending holder 22, one of the holders being provided with a centrally located opening 23, while the other is supplied with a vertical slot 24, the opening and slot being provided to receive the extending ends of thecustomary spring roller blind, indicated generally by the reference numeral 25. i

At the one'side of the frame I locatean adjusting rod 26 which has the upper end thereof passing upwardly within the guide 7 and mounted on the adjacent spindle 16 between the wheel and the traveler. The body of'the rod is carried within a fastener 2'? mounted on the frame. This fastener can be of any of the well known constructions, springloek, screw or otherwise, which will allow of the quick releasing and fastening of the rod in any adjustedposition.

When one wishes to use this appliance he simply releases the fastener 27 and forces the rod up or down, as wished. As the rod moves it forces the spindle 16, on which it is mounted, with it and in the same direction and accordingly causes the wheels to move up and down on the carrier plates. Owing to the teeth and the openings, the wheels always run evenly and true, that is to say, one side of the appliance cannot get ahead of the other. According to the position of the wheels, so the position ofthe travelers and consequently the adjustment bodily given the blind. Once the appliance has been adjusted, one can manipulate the blind in the usual way, drawing it partially or fully down, as the'occasion may require.

In Fig. 1 the attachmenthas been shown as adjusted in a position partially down from the top of the frame and the blind has been shown as partially pulled down, "In this position light can enter the room'at both the top and bottom of the window. Obviously, if one drew the blind fully down, light would be excluded at the bottom of the window,

while the room would be amply lighted with Inconnection with the guides, I wish itto be noticed that they could be placed on the opposing faces'bf the member 1 and 2 instead of on the inner faces where they are shown. To secure them on the opposing faces of the. frame it is only necessaryto fasten the back A of the guide to the'frame instead-of the plate 9 as shown; What I claim as my invention is 1. The combination with a window frame, upright opposing channel-iron guides 'secured to the frame and a vertically disposed rack associated with one of the flanges of each guide, of a cross member extending'bes tween the guides and presenting end spindles reduced in diameter in respect to the body of the cross member,.thereby forming shoulders, a pinion permanently secured to each spindle and operating on the adjacent- I rackand a traveler mounted freely on each spindlebetween the pinion and the shoulder and with the, sides thereof making sliding contact: with the flanges of the guides and fitted with outstanding horizontally disposed blind holders.

'- 2. The'combination with a window frame, upright opposing channel iron guides secured to the frame and a vertically disposed rack associated with one ofthe flanges of each guide, of a tube extending between the guides, end spindles permanently secured within the ends of the tubes and extending between the flanges of the guides, a pinion permanently secured to each'spindle and operating on the ad acent rack and a traveler mounted freely on each spindle between the pinion and the end of the tube and slidably received betweenthe flanges of the guides and provided with a substantially L-s'haped horizontally disposed extension forming a blind holder and with the neck of theyextension riding the inner face of the adjoinT ing guide flange.
